everyone was a newbie at once, and i believe they all should have the same chances like those previews newbies who now ranked up.
Chances to do what? Rank up?
You've been here since April and I don't think you understand why the merit system was put in place or why the 1-merit requirement to rank up to Jr. Member was implemented. You just said that shitposting noobs vastly outnumber the good ones--that's the exact reason why those things were done, and the problem was much, much worse before January 2018. The good noobs will rank up, the bad ones won't. That's fair, and I'll say it again: all noobs can post as they please.
Or did you mean noobs should have the same chance to join signature campaigns? It's not quite clear what you're arguing here.
